The purpose of this machine is to have props loaded at the mine entrance and transported directly to their respective working places by the machine itself. hen reaching the working place the machine will be lengthened out to its full capacity. Then with the endgate opened it gives free access to the carload of mine props and drilling equipment. The prop length will be measured by an assistant and called to the operator who will by that time have the prop holder set at a required prop length. The invention relates to the body and its appurtenances which are mounted on a constructed motor frame.

The plate or base 1,'Figure 3, is secured B0 to the motor frame. On this base are mounted two are plates or shoes 2 2, on which another pair of identical arc plates'or shoes 6, 6, Figure 10, slide during the time the'body is being revolved horizontally. The revolving of the body is accomplished by the gears 3, 3, 3, Figure 3, which are mounted on shafts 4, 4, 4, meshing with internal gear 7, Figure 10, and gear 5, Figure 10, which is turned by shaft 8, Figure 10, on which is worm gear 9, Figure 11, in mesh with worm 10, through which square shaft 11 slides as the table 65, Figure 1, is extended in or out of the body shell which is keyed to gear 13, which is in mesh with gear 14, Figure 14. Keyed on shaft 15, Figure 14, on which miter gear 16 is keyed, which is in mesh with miter gears 17 and 18. These gears 17 and 18 are not lreyed to shaft 19. but run free and are moved to a meshed position by slip collars in housings 20 and 21.

Gears 17 and 18 are rotated by being engaged respectively by slot clutches 22 and 23, which are engaged to their respective gears by lever 25, and connected to lever 26 by a rod. The arrangement so operates that when gear 17 and slot clutch 22 enter gear 18 and slot clutch 23, they disengage and have sufficient sliding room so that neither are in gear and the lever is left vertical. Shaft 19 may be disengaged from the source of driving power by the snap-in clutch 24, operated by lever 27, of a commercial type, making it unlikely to start the turning gears until desired as this disengages shaft 19 from gear 28, which is keyed to shaft 19. This is in mesh with gear 29, which is keyed to 30, and is connected to the driving power plant. The gear 31 is keyed to shaft 30, and in mesh with gear 32, which is free to turn on shaft 33, being connected to shaft 33 as desired by a snap-in clutch 34', which is operated by lever 35.

The gear engaging, disengaging and neutral arrangements in Figure 12 are identical in their workings. Shaft 33 turns sot clutches 36 and 37 and when engaged with miter gears 38'and 39 respectively, they cause miter gear 40 to rotate in the desired direc tions so as to cause the work table toberun out or in the body shell by revolving shaft .41, Figure 13, which is keyed to mitergears 40 and 42. Miter gear 42 is keyed to shaft 43, Figure 11, which is screw-threaded from thrust block 44 to the inner end of the shaft a portion of which is shown in Figure 11 by cutting away the guide pipe casing 53.

Shaft .43 has keyed to it miter gear '45, in mesh with miter gear 46, which is k-eyedto shaft 47 on which miter gear 48 is keyed and in mesh with miter gear 49, which keyed to screw shaft 50. ,7 This is identical with screw shaft 43 being a screw through thrust block'51 to its end which extends the full length ofthe body and encased in a guide pipe 52. When shaft 43, is rotated, shaft 50. has a similar movement in 'or out of the" thrust blocks 44 and 51. They have fired hearings to the body shell 110, while the shafts are attached to the work table 65. Fig 1. This causes the table to move as the shaft is thrust in'or out through theturning of shafts, 43 and 50, according to the direction of rotation.

During the time that the work table is beingrun in or out the pony truck, Figure 7,

- is in contact with the ground. to support the weight of the extended end of the work table.

The pony truck consists of a wheel 54 and its frame 55, and guide arms 56, 56, as a unit so as to revolve free of the attached end; to which is attached in line of the. guides a screw 57, which passes through the thrust screw and guide block shown in Figures 4 and 5, elevating or depressinga pony truck as desired by the turning of the hand wheel 58, which is fixed to'screw 57, in either direction as the pony truck is to be lowered or raised.

in Figure 4, the square holes 59, 59 are to hold guides'arms 56, 56, while they are allowed to slide up and down and as screw 57 is rotated through thrust block screw hole 60 causes an up and down motion as the thrust block, Figure 4, is secured to work table 65,

Figure 1; thereby transmitting thrust up or The circular cured to work table 65 by standards 66 66,,

Figure 1. Guard rail 63 differs from guard rail 64 in the respect that it is graduated in feet and inches of the zero mark being in alignment with the band saw 71, and the graduations increasing toward body shell 110,,

as shown in Figure 24, where; props are" stored. This enables the operator to set sliding prop holder 67 to be set at a desired prop length from the band saw 71, as the prop butt 1s snug 1n prop holder 67 and the end against prop stop 68, Figure 23. The band saw blade 116, Figure 2, is at the desired prop length ready to be cut. The prop hanger is held at a desired position on guide rails 63 and 69 by set screw 70, which is quickly set and loosenedby the crank arrangement as shown in Figure 23. v

The band saw 71 may be raised or lowered as shown in Figure 26, by the screw 72, which is keyed to miter gear 73, and is in mesh with miter gear 74, which is keyed on shaft 75. On 1 this the wheel 76 keyed and as the wheel is turned in the desired direction, the screw turns inthrust block arms 7 7 ,7 7 ,causing them to be raised or lowered and they are fastened to theband saw frame, causing it to be raised or lowered. to its desired position.

The carrying Jack consists of a frame 79, hexagon hollow screw 80, 1n whlch hexagon 81 is free to be raised or lowered, and is held in a desired position by'set screw 82, in cranr'r form which is easily and quickly set and loosened at will. The screw column 80 has a lug 83, which slides in a slot in the frame 79 as the column80 is raised or lowered preventing the screw 80 from turning on itslongitudinal axis as it is acted on by gear 84, whose center portion is the thrust block for screw 80. Gear 84 is in mesh with gear 85,

gear 87' is keyed meshing with'mitergear 88,

which iskeyed to shaft 86, to which miterwhich is keyed to shaft 89, which is connected to the traction motor of its driving power; the motor is reversible which gives a means of lowering and raising screw 80.

The collar 90 shown in Figure 19 is used to mount a drill upon and slides on the hexagon shaft 81, when it is extended and clamped by set screw 82. The screw is raised until the point 91 is firmly embedded in the roof by the upward pressure of thrust gear 84. When the collar is slipped to its desired elevation it. is held so by the set screw 92. Where by holding the drill in the desired working position the cap plate 115 takes the upward thrust of gears 8d and 85. This ack is located on the center line of the traction motor frame in front of the circular end of body shell as shown in Figure 1 where point 97 is exposed.

The jack head shown in Figures 15, 16, 17, consists of three arms 93 93 9 1, and the crossbar 95, which has an opening 96, to fit 97, the cylinder end of shaft 81. The arm 94: is provided with a rectangular opening 98 in which a lug 99 is connected to the screw 160, which uses crossbar 95, as a thrust block. Screw 100 is crank shaped on the end, and crank 101 provides means of turning screw 100, which moves lug 99 to and from crossbar and vertical rail stops 102, 102. The lug 99 is forced against the rail by screw as a vice holding the rail firmly against rail stops-102, 102 in its position to be raised to the roof by screw 80.

The endgate 105, Figure 8, is provided with suitable hangers for drill 103, drill post 10% and an extended electric cable 106 for carrying power to the drill. The endgate is on hinges 107, 107, the opening 108, 108 allowing endgate 105 to pass prop hanger and endgate latch 109 as it is slightly raised so as to be disengaged from square socket 111 and swung in line with body shell 110, Figure 2. After endgate 105 is closed it is locked by swinging prop hanger and latch 109, by being swung against the endgate and allowed to seat in socket 111. The sockets 61, 61, 61 are used to insert the swivel roller 162 shown in Figure 25. This roller facilitates the handling of barring rails.

The measuring gauge shown in Figure 22 has two pointed rods 83, 83 one in each end to insure measurement in loose material to a solid footing where prop is to be set, thus giving a measure to a firm base. The upper part- 85 may be raised or lowered and held as desired by set screw 84 in making measurements. The upper part 85 fits in to lower frame 86, making the measuring gauge c0mpact and protecting the upper end when the gauge is not in use.

In Figure 21, is shown the method of current supply of work table motor. The plug boxes 112 and 113 are connected by detachable electric cable 114. Plug box 112 is connected to traction motor fuse box by a suitable conductor supported by traction motor frame. This cable 114 shall be of such length that it will allow current to be supplied to the table motor when tables 65 is fully extended.

The reel of electric cable is usually placed on top of a mine motor frame as shown in Figures 1 and 2 as #117.

A steel box with a removable lid is to contain the detachable jack heads as shown by Figures 15, 16, 17 used to place bars and re movable rail roller 162, Figure 25. Figure 23 is to be secured to the platform on head end of the traction motor as shown in Figure 1 as #118. a

The motor mounted on work table will be encased in a metal box as shown in Figure 1, as 119, the fuse box located as 120, and the transmission in its box 121.
